  Consult Transaction Logs: Use transaction codes like FB03 (Display Document) or MB51 (Material Document List) to check the status of the document and its reversal history.
  Correct Posting: If you find that the record has been reversed, you may need to create a new posting or adjustment instead of attempting to reverse it again.
